pitrou opened a new issue, #45200: URL: https://github.com/apache/arrow/issues/45200
### Describe the enhancement requested Applying hadolint to Dockerfiles does not seem to improve our code quality. It however forces us to litter the Dockerfiles with comments to disable some rules. For example, hadolint is not able to expand variables, so every use of `FROM ${base}` gets flagged as [DL3006](https://github.com/hadolint/hadolint/wiki/DL3006). ### Component(s) Continuous Integration, Developer Tools -- This is an automated message from the Apache Git Service.
